## Agenda
### Thursday, June 1<sup>st</sup>
#### Atelier 1 - First steps with data preparation (9h-12h)
Here we will investigate the basic statistical properties and some feeling of the data. Do we have sufficient training points? Is the data stationary? What features will be relevant to solve the task at hand? Can we avoid overfitting?
-[Basics of programming with Python and scientific libraries](machine-learning/1_inspection/1_check_basics.ipynb)
If deep learning is powerful to solve a vast majority of problems, machine-learning approches, if successful, provide more insight about the physics at play for solving problems. We will investigate and criticize several supervised and unsupervised approaches to solve the task of classifying clouds of Lidar points (scenes) to infer the type of structure visible therein.

### Friday, June 2<sup>nd</sup>
#### Atelier 3: Deep Learning with Pytorch (9h-12h)
When the attempts to solve the problem are unsuccessful or if defining features is a challenge because of the input data's dimension, we can also learn the features that best solve the task. Here we will revisit the problem of Lidar with deep-learning approaches and see how we can efficiently design a neural network to solve the classification task.

-[MNIST classification with a convolutional neural network](deep-learning/session_1b_cnn.ipynb)
-[Understanding and training PhaseNet on a local dataset](deep-learning/session_2_phasnet.ipynb)
🍴 Lunch break and posters (12h-14h)
#### Atelier 4: Deeper dive in artificial intelligence (14h-15h30)
This last class will be a free hands class on various problems. We invite people to bring datasets and tasks of interest so we can sit and try machine-learning solutions for solving them. We will also dive deeper into algorithms, try to improve performances and discuss some good practices in machine and deep learning.
